[Boatanchors] Tube reciever design banter

[Drew P.]

Carl,

I note that you express a preference for the 6GM6 as a first (and only) RF amplifier stage. How does the performance (noise figure, gain, intermod susceptibility, AGC control range) of the semiremote cutoff 6GM6 pentode compare to that of a cascode variable mu twin triode such as the 6ES8 and a few other types?

It appears that TV front end design at the end of the tube era seemed to diverge along those two lines.
